Blood meal cannabis
blood meal is sometimes not recommended for organic gardening because it can damage young tender plants in warm moist conditions see below .
Analysis – nitrogen 13.25, phosphorus 1.00, potassium 0.60.
Source – slaughterhouses make dried blood as a by-product of animal processing. A wide selection of blood fertilizer products is now available.
Release Rate – rapid lasts up to 4 months. Suited to fast growing seasonal green vegatables.
Application – no more than 4oz per square yard during growth. Apply during the growing season.
Soil Reaction – acidic.
BLOOD MEAL IS USEFUL FOR
- Sprinkle over compost heap if high carbon content brown matter e.g. paper, chipped twigs, straw. etc, is in excess of nitrogenous green leafy matter.
- Can be incorporated to balance the carbon content when digging in a high carbon brown mulch – othewise nitrogen is robbed from the soil.
- Use on nitrogen hungry greens:- courgette, marrow, lettuce, – perhaps corn cob initially, and greens such as kale, brussel sprounts and cabbage. However the acidic soil reaction makes it somewhat less than ideal for the cabbage family.
- Apply during the growing season.
- Also used to repel animals like deer and rabbits, but only effective if it remains dry. I suggest placing it in containers.
Action On Plants – the analysis shows that nitrogen is the major constituent due to the protein content.
These blood proteins are rapidly broken down by soil bacteria to ammonia. In warm moist conditions that favour bacterial growth, decomposition of this organic fertilizer can be too rapid. Ammonia may be released in large enough quantity to damage delicate roots.
Plant roots absorb ammonia to take up nitrogen for building plant protein. Therefore blood meal is useful for plants that add lots of green leafy growth.
As it is a fast acting organic feed, care should be taken not to apply too much, especially in warm moist conditions. Blood Meal can also be used to effectively balance carbons in the compost heap or when digging fresh organic matter into the ground.
- Don’t apply to seedlings.
- A fast acting organic feed and care should be taken not to apply too much. Rapid decomposition when conditions are warm and moist could be damaging.
- Don’t apply to peas and beans and other legumes. They have root nodules with bacteria that fix atmospheric nitrogen.

How often to add Blood or Bone Meal?
- Nov 29, 2012
Hello fellow growers. This is my first grow and first thread post
Soil: 50% – Miracle Grow Premium Potting Soil, 20%- Sphagnum Peat Moss, 30% – Perlite
Light: 18/6(veg), 8 – 23watt(1600 lumen, 5K) CFL
Temp: 76f average (68 low, 81 high)
Strain: Random Seed Bag(2 sativa, 3 indica – or so it seems as of now)
It was slow going due to first time grower mistakes I made. I’ve finally got my grow area to acceptable(optimal?) conditions and have started fertilizing my seedlings. I’m using Blood Meal(12-0-0, veg), Bone Meal(6-9-0, flower) and Kelp Meal(1-0-2, throughout?) I started @ 1/3 strength fert of Kelp Meal and Blood Meal as of now and have only admistered the fert once.
So my question is this, how often should I add the Kelp & Blood Meal? I’m uncertain of how long these ‘slow’ release fertilizers will take to disintergrate and no longer benefit my plants. Is this a once and done type of fertilizing that can wait until next repot? Also, does anyone know if it is possible to fertilize with Blood/Bone Meal through watering like other nutrient solutions? I know they will dissolve in water but I am uncertain if plants will still receive the same benefits when administering as a liquid nutrient.
I’ve already been astonished at the speed that my plants use nutrients and grow on several occasions. Thanks in advance for any help and may you all have healthy greens & bountiful yields!
